7 DevSecOps Engineer Interview Questions and Answers

Introduction

This question assesses your understanding of DevSecOps principles and the importance of security within the software development lifecycle.

How to answer

• Define what DevSecOps means and how it differs from traditional DevOps
• Explain the key benefits of integrating security early in the development process, such as reducing vulnerabilities and compliance costs
• Discuss how security practices can enhance collaboration between development, operations, and security teams
• Mention specific tools or practices that facilitate this integration, like automated security testing and continuous monitoring
• Illustrate your answer with an example or a case study if possible

What not to say

• Suggesting that security is only the responsibility of a separate team
• Failing to mention specific DevSecOps tools or practices
• Overlooking the importance of collaboration between teams
• Making vague statements without explaining their significance

Example answer

“Integrating security into the DevOps process is crucial because it shifts security left, allowing teams to identify and mitigate vulnerabilities early in the development lifecycle. This not only reduces the risk of security breaches but also lowers remediation costs significantly. For example, using tools like Snyk for automated dependency scanning helps developers catch vulnerabilities before they reach production, fostering a culture of shared responsibility among development, operations, and security teams.”
